Technical Abstract

An image processing apparatus includes circuitry configured to receive a designation of a to-be-corrected color that is a process color or a special color different from the process color and is to be corrected; identify, on the basis of the designation, a tone correction pattern, and generate rendering data of the tone correction pattern to be used for forming an image on a recording medium; obtain a standard value of the to-be-corrected color; and correct the to-be-corrected color on the basis of a difference between a color measuring result obtained from measuring a color of the image, of the tone correction pattern formed on the recording medium and the standard value.

6 claims

Legal claims defining the scope of protection, as filed with the USPTO.

1

1. An image processing apparatus comprising: circuitry configured to receive a designation of a to-be-corrected color that is a process color or a special color different from the process color and is to be corrected; identify, on the basis of the designation, a tone correction pattern, and generate rendering data of the tone correction pattern to be used for forming an image on a recording medium; obtain a standard value of the to-be-corrected color; and correct the to-be-corrected color on the basis of a difference between a color measuring result obtained from measuring a color of the image of the tone correction pattern formed on the recording medium and the standard value, wherein the image processing apparatus further comprises: a display unit, wherein the circuitry is further configured to cause the display unit to display, as choices of combinations for the to-be-corrected color, to select “CMYK” or “CMYK+Special color”, and not to select a choice of only the special color, when a special color of a fluorescent color is used.

2

2. The image processing apparatus according to claim 1 , further comprising: a display unit, wherein the circuitry is further configured to cause the display unit to display, as a choice or choices for the to-be-corrected color, the process color, the special color, or a combination of the process color and the special color.

3

3. The image processing apparatus according to claim 2 , wherein the special color includes white.

4

4. An image processing system comprising: receiving circuitry configured to receive a designation of a to-be-corrected color that is a process color or a special color different from the process color and is to be corrected; rendering data generating circuitry configured to identify, on the basis of the designation, a tone correction pattern, and generate rendering data of the tone correction pattern; tone characteristic obtaining circuitry configured to obtain a standard value of the to-be-corrected color, image forming circuitry configured to form an image of the tone correction pattern on a recording medium; and tone correction circuitry configured to correct the to-be-corrected color on the basis of a difference between a color measuring result obtained from measuring a color of the image of the tone correction pattern formed on the recording medium and the standard value wherein the image processing system further comprises: a display unit, and displaying circuitry configured to cause the display unit to display, as choices of combinations for the to-be-corrected color, to select “CMYK” or “CMYK+Special color”, and not to select a choice of only the special color, when a special color of a fluorescent color is used.

5

5. A non-transitory recording medium storing a program, when executed by a processor of an image processing apparatus, causing the processor to implement an image processing method, the image processing method comprising: receiving a designation of a to-be-corrected color that is a process color or a special color different from the process color and is to be corrected; identifying, on the basis of the designation, a tone correction pattern, and generating rendering data of the tone correction pattern to be used for forming an image on a recording medium; obtaining a standard value of the to-be-corrected color; and correcting the to-be-corrected color on the basis of a difference between a color measuring result obtained from measuring a color of the image of the tone correction pattern formed on the recording medium and the standard value, wherein the method further comprises: causing a display unit to display, as choices of combinations for the to-be-corrected color, to select “CMYK” or “CMYK+Special color”, and not to select a choice of only the special color, when a special color of a fluorescent color is used.

6

6. The image processing apparatus according to claim 1 , wherein the circuitry is configured to cause the display unit to display to select “CMYK”, “CMYK+Special color” or “Special color only” when the special color excluding the fluorescent color is used.
